Defined in header <stop_token>
template < class T, class CallbackFn >
using stop_callback_for_t = T :: template callback_type < CallbackFn > ;
(since C++26)

The alias template stop_callback_for_t is used to obtain the stop callback type of the type T .

Notes

The corresponding stop_callback_for_t for standard stop token types and any valid CallbackFn are:

  • specialization of std:: stop_callback for std:: stop_token ,
  • specialization of std :: inplace_stop_callback for std :: inplace_stop_token , and
  • unspecified type without stoppable callback registration and deregistration for std :: never_stop_token .
